The origin of sickle cell anemia
WebbSickle cell anemia: a look at the connection between DNA and phenotype. Genes are translated into proteins; mutations often (but not always) result in changes in the sequence of amino acids in those proteins. Changes in the amino acid sequence can modify (in various ways) or even completely destroy protein function. WebbSickle cell disease can also sometimes cause a wide range of other problems. These include: delayed growth during childhood and delayed puberty. gallstones, which can cause tummy (abdominal) pain and yellow skin and eyes (jaundice) bone and joint pain. a persistent and painful erection of the penis ( priapism ), which can sometimes last …
